Hope your CatChaser survived the attack! :) Remember: Dogs run, Cats attack.<BR/><BR/>As for your question - the greater than- less than drop-down box has no effect. You just leave it alone. The value the Ultrasonic sensor block receives from the Compass sensor is output from the Data Hub... you can see that I've dropped a data line out of it and into a MATH block (to multiply by 2)... I then take that value and it becomes output into the Number-to-Text block... and on and on...<BR/><BR/>As for the RIF... I hadn't looked in on the blog for a few days, but I just took a look... definitely some good info in there. I haven't decided if I'll sign up yet - need more info! (Here me, Poe - more info!)<BR/><BR/>Send me a picture of your CatChaser when you can...<BR/><BR/>JimJim Kellyhttps://www.blogger.com/profile/13876934942928389738noreply@blogger.comtag:blogger.com,1999:blog-21402852.post-1156800892465357652006-08-29T07:34:00.000+10:002006-08-29T07:34:00.000+10:00Hya Jim!

I emailed you last week about my Catchaser robot :)<BR/><BR/>Thanks for posting the snapshot of the program but I have a question. When you set the ultrasonci sensor to centimeters what did you do with the greater/less than thing?<BR/><BR/>To the whole team: great blog! I check it every day. And in case you haven't seen it, they posted a whole bunch of info on the RIF on the blog.rifagent.com site. Are you goign to join it?<BR/><BR/>DaveAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-21402852.post-1156776319664585232006-08-29T00:45:00.000+10:002006-08-29T00:45:00.000+10:00100 is the maximum power you can command the motor...100 is the maximum power you can command the motor to. All motors have some maximum power, and at a NXT-G setting of 100 the NXT will try to drive the motor with every amp & volt it legally can.<BR/><BR/>If you need more speed or more torque (power), try gearing the motor output to run slower (and thus with more power, or torque), or gear it to run faster (but with consequently less force... there ain't no such thing as a free lunch).<BR/><BR/>-- <BR/>Brian "at BrickFest sleep is for the weak" DavisBrian Davishttps://www.blogger.com/profile/13348160352741782598noreply@blogger.comtag:blogger.com,1999:blog-21402852.post-1156734796555041492006-08-28T13:13:00.000+10:002006-08-28T13:13:00.000+10:00The only way I could find out how to increase the ...The only way I could find out how to increase the speed of the motors is through gearing.<BR/>Im pretty sure you cant increase it past 100 (at least in NXT-G, dont know about anything else).msimnoreply@blogger.comtag:blogger.com,1999:blog-21402852.post-1156726690582209442006-08-28T10:58:00.000+10:002006-08-28T10:58:00.000+10:00Cool blog and I love the idea's.
